Electronic scanning precision measurement radar system and target tracking method

摘要

PROBLEM TO BE SOLVED: To provide an electronic scanning precision radar system of high reliability capable of enhancing calculation precision of a predicted position for a tracking target.;SOLUTION: Two tracking jobs of a tracking 1-1 and a tracking 1-2 are allocated to detect the position and a speed of the target in the one target, by raising up pseudo-updating rate doubly in a search period, and the predicted position in the next scanning is calculated based on the up-to-date positions and speeds of the target detected by the tracking 1-1 and the tracking 1-2. The predicted position is calculated based on one out of the two tracking jobs of the tracking 1-1 and the tracking 1-2, when a coast is generated in the other thereof. The electronic scanning precision radar system has a function capable of calculating only a distance as the predicted position for the target, by selection-assigning the target at the time of the final landing advance as the target of the tracking object, by a radar display part, and capable of switching to processing of fixing an angle of elevation on a glide path GP and an azimuth angle on a coarse line CL to calculate the predicted position.;COPYRIGHT: (C)2008,JPO&INPIT
